SEANK.

Application filed November ing as a base for, a sectional heel-reinforcing tube.

My invention relates to the prevention of breakage of the heel, to making the shoeshank rigid and arch-sustaining, and to strengthening that portion of the shoe sole beneath the anterior metatarsal arch of the wearers foot, without impairing the flexibility of the shoe sole.

Drawings.

In the drawings- Fig. 1 is a longitudinal vertical sect-ion of that portion of a shoe to which the device of my invention relates.

Fig. 2 is a top plan view of the reinforcing plate.v s

Fig. 3 is a top plan view of the tapering tube tip which telescopes the heel reinforcing J tube.

Fig. 4 is a top plan view of the heel pla-te.

Fig. 5 is a top plan view of the plate embedded in the rubber heel lift.

Fig. 6 is an enlarged sectional fragmental illustration of the heel, with the rubber heel lift and its retaining screw removed showing the remaining parts as held in their assembled positions.

Description.

anterior metatarsal arch of the wearer, its

contour being suggestively outlined in Fig. 2. The shoe heel B has a bottom Cavity 15 for the reception of the plate 16, that plate 16 being perforated at 17. The perforations 11 and 17 are in alinement with each other and with the heel-bore 18, and a tube 19 is seated in that bore 18 as shown in Fig. 1.

The screw 20 extends from the plate A. to the heel-lift-plate C and its lower terminal 5, 1925. Serial No. 66,937.

engages the screw-threaded boss 21 in said plate C, the plate C being embedded in the rubber lift or heel-tip D as shown in Fig. 1. A telescoping section 22 is driven on the upper end of the tube 1S) as shown in Fig. 1

to form an extension of that tube, and to hold the bottom plate 16 in place within the heel-recess 15, and to secure the whole of the heel structure firmly to the heel-por tion 10 of the plate A, the conical tips E, E are driven into the tube 19 and section 22.

The upper tip E Shown in Figs. 1 and 6 is driven through the insole 23 into the open mouth of the section 22 to form a seat for the head of the screw 2O which will be flush with the surface of the insole 23.

The plate C is contoured as shown in Fig 5, its body 24 and peripheral liange 25 registering with the cupped cavity 26 and outer flange 27 of the plate 16.

When the resilient heel lift D becomes worn or run over, rights and lefts may be interchangeable, or new liftsD installed, by the simple manipulation of the screw 20.

My construction secures continuous reinforcement of all of the. described contiguous parts of the shoe, viz,-the rubber heel lift, the heel, the shank and the sole; it insures strict and true alinement of those parts with each other; it stiifens the shank, prolongs the life of the sole; and renders the rubber heel lifts readily replaceable and interchangeable by the simple operation of a single screw.

The improvement in shoes comprising a plate contoured at its rear end to fill the heel of the shoe and at its front end to extend the width of the interior of the shoe beneath the anterior metatarsal arch of the wearer; a heel having a central bore and a bottom cavity; a plate mounted in said cavity and having a perforation in alinement with said bore; a resilient heel lift having embedded therein a heel-lift-plate litting within said first-named plate and having a screw-threaded boss in alinement with said bore and perforation; and a screw extending from the interior of the shoe through said bore and perforation and into said boss.

In testimony whereof I hereunto affix my signature.

JOSEPH M. OZEE.
